2017-01-01update copyright year range in GDB filesJoel Brobecker14-14/+14
This applies the second part of GDB's End of Year Procedure, which updates the copyright year range in all of GDB's files. gdb/ChangeLog: Update copyright year range in all GDB files.
2016-08-16sim: m68hc11: use standard STATIC_INLINE helperMike Frysinger2-25/+34
Rather than redefine inline locally, use the common STATIC_INLINE.
2016-08-15sim: unify symbol table handlingMike Frysinger2-37/+18
The common sim tracing code already handles loading and tracking of symbols from the target program so that it can show symbol info in trace/disassembly calls. Once we touch up the trace code and add a few API callbacks, ports don't need to do loading and searching of symbol tables themselves anymore.
2016-08-13sim: m68hc11: standardize sim_cpu namingMike Frysinger10-347/+366
We use "sim_cpu *cpu" in the sim code base, not "struct _sim_cpu" or the name "proc", so clean up this sim to follow along.
2016-08-13sim: m68hc11: fix up various prototype related warningsMike Frysinger8-12/+29
A few funcs are only used locally, so mark them static to avoid warnings due to -Wmissing-prototypes. Some funcs cast the return value wrong, so drop them (and let void * just work by default). Update some prototypes to be new style.
2016-01-10sim: move many common settings from CPPFLAGS to config.hMike Frysinger3-68/+124
Rather than stuffing the command line with a bunch of -D flags, start moving things to config.h which is managed by autoheader. This makes the makefile a bit simpler and the build output tighter, and it makes the migration to automake easier as there are fewer vars to juggle. We'll want to move the other options out too, but it'll take more work.
2016-01-10sim: drop unused SIM_AC_OPTION_PACKAGESMike Frysinger2-7/+6
This was imported from the ppc sim, but that was only used to control a single file, and that is already governed by the hw models. There's no need to have a sep configure option here, especially since none of the other sims are using it. Even when the code is enabled, there's no runtime overhead.
2016-01-10sim: allow the environment configure option everywhereMike Frysinger2-2/+28
Currently ports have to call SIM_AC_OPTION_ENVIRONMENT explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
2016-01-10sim: allow the assert configure option everywhereMike Frysinger2-2/+23
Currently ports have to call SIM_AC_OPTION_ASSERT explicitly in order to make the configure flag available, which none of them do. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports.
2016-01-10sim: drop targ-vals.def->nltvals.def indirectionMike Frysinger2-57/+5
We don't have alternative nltvals.def files, so always symlinking the targ-vals.def file to it doesn't gain us anything. It does make the build more complicated though and a pain to convert to something newer (like automake). Drop the symlinking entirely. In the future, we'll want to explode this file anyways into the respective arch dirs so things can be selected dynamically at runtime, so it's not like we'll be bringing this back.
2016-01-10sim: allow the inline configure option everywhereMike Frysinger3-49/+39
Currently ports have to call SIM_AC_OPTION_INLINE explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
2016-01-10sim: drop --enable-sim-{regparm,stdcall} optionsMike Frysinger2-12/+6
These options were never exposed for most sims (just the ppc one), and they are really only useful on 32-bit x86 systems. Considering modern systems tend to be 64-bit x86_64 and how well modern compilers are at optimizing code, these have outlived their usefulness.
2016-01-10sim: drop --enable-sim-cflags optionMike Frysinger2-23/+6
No other sub directory provides such a configuration option, so drop it from the sim dir as well. This cleans up a good bit of code in the process. If people want to use custom flags for just the sim, they can still run configure+make by hand in the sim subdir and use the normal CFLAGS settings.
2016-01-09sim: drop common/cconfig.h in favor of a single config.hMike Frysinger3-3/+406
The common subdir sets up a cconfig.h file to hold checks for the common code. In practice, most files still end up using config.h instead which just leads to confusion. Merge all the configure checks that went into cconfig.h into SIM_AC_COMMON so we can drop the cconfig.h file altogether. Now there is only a single config.h file like normal.
2016-01-06sim: sim_{create_inferior,open,parse_args}: constify argv/env slightlyMike Frysinger2-2/+7
2016-01-03 Mike Frysinger <vapier@gentoo.org> * sim-options.c (sim_parse_args): Mark argv array const. * sim-options.h (sim_parse_args): Likewise.
2016-01-04sim: punt x86-specific bswap logicMike Frysinger2-21/+6
The compiler/C library should produce reasonable code for htonl/ntohl, and at least glibc tries pretty hard to always produce good code for them. This logic only had support for 32-bit x86 systems anymore, and it's unlikely people were even opting into this, so drop it all.
2016-01-03sim: parse_args: display getopt error ourselvesMike Frysinger2-3/+5
Fix a long standing todo where we let getopt write directly to stderr when an invalid option is passed. Use the sim io funcs instead as they go through the filtered callbacks that gdb wants.
2016-01-03sim: clean up some more device detritusMike Frysinger2-1/+4
Clean up some more remains of WITH_DEVICES that escaped notice. We also clean up GETTWI/SETTWI defines in a few ports where they were copied & pasted and are unused as they happen to be near the device code.
2016-01-03sim: drop host endian configure optionMike Frysinger3-261/+232
The --enable-sim-hostendian flag was purely so people had an escape route for when cross-compiling. This is because historically, AC_C_BIGENDIAN did not work in those cases. That was fixed a while ago though, so we can require that macro everywhere now and simplify a good bit of code.
2016-01-03sim: convert to bfd_endianMike Frysinger3-19/+24
Rather than re-invent endian defines, as well as maintain our own list of OS & arch-specific includes, punt all that logic in favor of the bfd ones already set up and maintained elsewhere. We already rely on the bfd library, so leveraging the endian aspect should be fine.
2016-01-01GDB copyright headers update after running GDB's copyright.py script.Joel Brobecker14-14/+14
gdb/ChangeLog: Update year range in copyright notice of all files.
2015-12-30sim: m68hc11: fix default endianMike Frysinger3-2/+7
The previous commit here set the default to little instead of big. A typo lost when reviewing the different targets in parallel.
2015-12-30sim: cris/m68hc11: move default endian/alignment to configureMike Frysinger4-6/+58
2015-12-30sim: arm/d10v/h8300/m68hc11/microblaze/mips/mn10300/moxie/sh/v850: convert ↵Mike Frysinger2-9/+18
to common sim_{fetch,store}_register
2015-12-27sim: unify sim-hloadMike Frysinger2-1/+4
Pretty much all targets are using this module already, so add it to the common list of objects. The only oddball out here is cris and that's because it supports loading via an offset for all the phdrs. We drop support for that.
2015-12-26sim: punt WITH_DEVICES & tconfig.h supportMike Frysinger3-6/+6
No arch is using this anymore, and we want all new ports using the hardware framework instead. Punt WITH_DEVICES and the two callbacks device_io_{read,write}_buffer. We can also punt the tconfig.h file as no port is using it anymore. This fixes in-tree builds that get confused by picking up the wrong one (common/ vs <port>/) caused by commit ae7d0cac8ce971f7108d270c. Any port that needs to set up a global define can use their own sim-main.h file that they must provide regardless.
2015-12-24sim: make LMA loading the default for all targetsMike Frysinger2-2/+4
Most targets already default to loading code via their LMA, but for a few, this means the default changes from loading VMA to LMA. It's better to have the different targets be consistent, and allows some code clean up.
2015-12-24sim: enable watchpoint module everywhereMike Frysinger2-1/+4
We build & bundle the watchpoint module everywhere, but we don't make the command line flags available by default. A few targets opted in, but most did not. Just enable the flag for everyone. Not all targets will respect the flags (making them nops), but shouldn't be a big deal. This is how we handle other common modules already.
2015-11-17sim: always enable modulo memoryMike Frysinger2-1/+4
Having this be a config option doesn't make sense: the code size is pretty much the same (as all the logic is still active), and if it's disabled, the sim throws an error if you try to use it. That means we can't break sims that weren't using it before by enabling it all the time.
2015-11-16sim: sim-stop/sim-reason/sim-reg: move to common obj listMike Frysinger2-2/+4
Now that all arches (for the most part) have moved over, move sim-stop.o, sim-reason.o, and sim-reg.o to the common object list and out of all the arch ports.
2015-11-15sim: clean up redundant objectsMike Frysinger2-1/+4
Some of the target makefiles listed objects that were already pulled in via SIM_NEW_COMMON_OBJS. Clean those up.
2015-11-15sim: sim-close: unify sim_close logicMike Frysinger2-16/+4
Other than the nice advantage of all sims having to declare one fewer common function, this also fixes leakage in pretty much every sim. Many were not freeing any resources, and a few were inconsistent as to the ones they did. Now we have a single module that takes care of all the logic for us. Most of the non-cgen based ones could be deleted outright. The cgen ones required adding a callback to the arch-specific cleanup func. The few that still have close callbacks are to manage their internal state. We do not convert erc32, m32c, ppc, rl78, or rx as they do not use the common sim core.

2015-06-23sim: use AS_HELP_STRING everywhereMike Frysinger2-11/+23
This helps standardize the configure --help output.
2015-06-12sim: update configure.in->configure.ac docsMike Frysinger2-1/+5
A few places still refer to the configure.in file; update them.
2015-06-12sim: drop -DTRACE from configureMike Frysinger2-3/+7
No code uses this anymore and the symbol conflicts with the new TRACE helper. Punt it from configure.
2015-06-11sim: m68hc11: delete unused interrupt_namesMike Frysinger2-8/+4
The interrupts.c file has a static/fuller definition that is used, so drop this copy in interp.c.
2015-06-11sim: m68hc11: switch to common sim_resumeMike Frysinger3-77/+7
This code already matched the common sim reusme logic, so we can simply drop it and pull in the common code.
2015-06-11sim: m68hc11/mn10300/v850: delete redundant INLINE definesMike Frysinger2-8/+4
The sim-inline.h header already takes care of this for us, so punt the local definitions.

2015-04-18sim: unify SIM_CPU definitionMike Frysinger2-3/+4
Since every target typedefs this the same way, move it to the common code. We have to leave Blackfin behind here for now because of inter-dependencies on types and headers: sim-base.h includes sim-model.h which needs types in machs.h which needs types in bfim-sim.h which needs SIM_CPU.
2015-04-18sim: unify sim_cia definitionMike Frysinger2-2/+4
Almost every target defines sim_cia the same way -- either using the address_word type directly, or a type of equivalent size. The only odd one out is sh64 (who has 32bit address_word and 64bit cia), and even that case doesn't seem to make sense. We'll put off clean up though of sh64 and at least set up a sensible default for everyone.
2015-04-17sim: replace CIA_{GET,SET} with CPU_PC_{GET,SET}Mike Frysinger2-3/+4
The CIA_{GET,SET} macros serve the same function as CPU_PC_{GET,SET} except the latter adds a layer of indirection via the sim state. This lets models set up different functions at runtime and doesn't reach so directly into the arch-specific cpu state. It also doesn't make sense to have two sets of macros that do exactly the same thing, so lets standardize on the one that gets us more.
2015-04-15sim: unify sim-cpu usageMike Frysinger3-7/+5
Now that all the targets are utilizing CPU_PC_{FETCH,STORE}, and the cpu state is multicore, and the STATE_CPU defines match, we can move it all to the common code.
2015-04-13sim: fix the PKGVERSION defineMike Frysinger2-2/+6
This should be SIM, not GDB.
2015-04-13sim: m68hc11: convert to sim-cpuMike Frysinger4-11/+48
Make cpu allocation fully dynamic so we can leverage the common sim-cpu and its APIs.
2015-04-06sim: move sim-engine.o/sim-hrw.o to the common listMike Frysinger2-2/+4
This makes these two objects available to all sims by default.
